Seed Swaps

Cornflower, Bachelor's Buttons 'Blue Boy'     

I spread some Botanical Interests seed in the bed last season and a number came up. I had 3 big stands of it. I let it go to seed. I collected the seed but of course some fell on the bed. Now cornflowers are coming up in many places. I don’t know if I’ll be able to thin them without disturbing some of the chrysanthemums.
